Synthesis of (±)-zearalenone

Tetrahedron, 1987
AbstractThe key intermediate (XId) in the synthesis of the title compound (XIII), which has anabolic and uterotropic activity, is prepared starting from the pyran (I).

Occurrence of zearalenone in maize [PDF]

Mycotoxin Research, 1993
The occurrence of zearalenone in whole plants and parts of maize usually used for silage making was investigated during the cultivation period of the crop.Zearalenone was detected upto several hundreds of μg/kg DM, that mainly accumulated at the end of the ripening process thus contaminating the silages subsequently.

Zearalenone production in barley

Annals of Applied Biology, 1975
SUMMARY A plot of barley cv. Golden Promise was sprayed with an isolate of Fusarium culmorum known to produce zearalenone, an oestrogenic toxin. The grain was harvested and stored under conditions that were known to induce toxin production in sterilized grain inoculated with the same strain. Toxin was not found in the harvested grain but appeared 20

Microbial cleavage of zearalenone

Xenobiotica, 1988
1. Zearalenone, a fungal oestrogenic compound, was subjected to microbial transformation studies. Preliminary screening with 150 fungal species showed that Gliocladium roseum was capable of metabolizing zearalenone in 80-90% yields. 2. Large-scale fermentation with G. roseum produced a 1:1 mixture of 1-(3,5-dihydroxyphenyl)-10'-hydroxy-1-undecen-6'-one

Zearalenone: Undesirable Substance [PDF]

, 2009
The presence of toxic or undesired substances in plant material can disturb homeostasis in both humans and animals (Massart et al. 2008; Shephard 2008b). These toxins enter the organism via the gastrointestinal tract, resulting in numerous adverse consequences (Cavret and Lecoeur 2006; Sergent et al. 2008).

Urinary zearalenone measured with ELISA as a biomarker of zearalenone exposure in pigs

Mycotoxin Research, 2014
The suitability to assess zearalenone (ZEA) exposure in pigs of a commercial ELISA kit for ZEA analysis in urine was tested. A daily dose of 0, 5, 10, 20 and 40 μg synthetic ZEA per kilogram BW was administered via the feed to four gilts per dose group, and after 3 and after 7 days of ZEA intake, urine samples were assayed with the ELISA which has a ...

Effects of Processing on Zearalenone

2002
Zearalenone (ZEN), a common contaminant of all major cereal grains worldwide, is produced by some plant pathogenic molds including Fusarium graminearum and F. culmorum. The biological activity of this mycotoxin is mainly attributed to its estrogenic activity that modulates/disrupts endocrine function in animals and possibly humans.

Aptamer-Based Lateral Flow Test Strip for Rapid Detection of Zearalenone in Corn Samples.

Journal of Agricultural and Food Chemistry, 2018
An aptamer-based lateral flow test strip was developed for the detection of zearalenone (ZEN). This assay was based on the competition for the aptamer between ZEN and its complementary sequence.

Investigations on metabolism of zearalenone in broilers

Mycotoxin Research, 2000
Two experiments were carried out with male broilers to examine excretion kinetics of zearalenone (ZEA) and its metabolites (Exp. 1) and their occurrence in blood plasma and bile fluid (Exp.2) after a single oral dose of ZEA (approximately 6 µg/kg body weight) from naturally contaminated wheat.
